IMPROVEMENT IN VEH ICLE=AXLE LUBRICATORS.

Specification formin'g part of Letters Patent N 0. 207,195, dated August20, 1878 application filed May 11, 1878.

skein is provided with an oil-reservoir, which may be cast in one piecewith the skein or attached separately, as may be preferred. Thisoil-reservoir G is here represented as fittin in the space between theaxle A and bolster communicates, by means a of a' tube, g, with anoil-chamber, consisting of a recess, H, formed in the upper surface ofthe journal of the axle.

In the jskein D, immediately over a portion of this oil-chamber, is anopening, provided with a cap or cover, D which is made to fit closely,so as to be oil-tight, and is held in place by screws, so that it may beremoved when desired. The cap D carries two pup pet-valves, I I, whichare held snugly in their seats by springs t z coiled around their stems.

he upper end of the tube 9 connects with the reservoir Gthroughaperforated cylinder,

, which serves as the valve-seat for a valve,

J, of a piston-like form, worhmg in said cyl- To all whom it mayconcern:

Be it known that I, ROBERT R. MOORE, of Lewisville, in the county of LaFayette and State of Arkansas, have invented new and useful Improvementsin Axles, of which the following is a specification:

y invention relates particularly to means for lubricating the axles ofvehicles; and it parts, as hereinafter particularly described and setforth.

he manner of carrying out my invention is illustrated in theaccompanying drawing, in which Figure 1 is a longitudinal verticalsection of a portion of an axle embodying my improvements; and Fig. 2, atop View of the same.

Similar letters of reference indicate corresponding parts.

he axle A, hounds B, and bolster C may be of any suitable description.The thimbleis pivoted to the short arm of a lever, L, havskein D isprovided witha flange or shoulder,

ing its fulcrum in an arm, I, projecting from the'side of the reservoir.

The long arm of the lever L is connected to holding it in place by meansof bolts E The bolt E has a head at one end and an eye at the other, andthe bolt E has a head at one end and a screw-thread at the other. Thebolt E is passed through the lug d in a horizontal direction until itshead bears against the lug, and the bolt E is passed downward throughthe bolster, hounds, and axle, with its head bearing against the top ofthe bolster and its lower end engaged with the eye of the bolt E, whereit is secured by a nut, and by this means the skein is held securely inplace.

piece, m which, with the protruding portion of the rod or pin, iscovered with a semi-tuba lar cap, m attached to the reservoir.Surrounding the inner portion of the rod or pin m is a coiled spring,02, which is stronger than the combined strength of the two springs z1', surrounding the stems of the valves I I. The reservoir is suppliedwith oil through a screw-cap, Q, of any suitable description.

When it is desired to supply oil to the axlejournal, the rod or pin m ismoved inward by pressing on the thumb-piece m so as to operate thelevers L L and raise the pistonvalve J above the perforations k, toallow oil to ter of the axle for a distance equal to or greater than thelength of the skein, with its head bearing against the outer end of theaxle and its inner end secured by a nut, f, inserted in greatly to thestrength of the axle when the latter is made of wood.

The upper portion of the inner end of the der K and through the tube 9to the oilchamber or recess H. The button is then released, whereuponthe action of the spring seats, so as to allow oil to flow to thebearingmodified, so as to adapt it to iron-axles of ll-immediatelyreturn. the parts to the former position. As the spring a is strongerthan the combined strength of the two springs i i, and J fits thecylinder 70 with pistonlike nicety, the effect of the action of thespring a is to force the valves I I upward from their as new and desireto secure by Letters Patent- 1. The recess or oil-chamber H, formed inthe upper surface of the axle-journal, in combination with the skein D,cap or cover D and valves I I, substantially as and for the purposeshown and described.

2. The tube 9 and cylinder K, in combination with the oil-reservoir Gand oil-chamber H, substantially as and for the purpose shown anddescribed.

3. The combination of the cylinder K, havin g the perforations 7c, thepiston or valve J, orking in said perforated cylinder or valveat theconnecting-tube g, the oil-chamber and the valves I I, substantially asand for h purpose shown and described.

{.i'The combination of the rod or pin on and surfaces of the skein andaxle-box, and thoroughly lubricate them. When sufficient oil hasescaped, the springs i t return the valves IIto their seats. Thesevalves are so arranged in their seats as to rise only sufficiently highto allow the oil to escape, but not high enough to obstruct the properworking of the bearin gsurfaces or to collect and become clogged by anygummed oil which may have collected on said surfaces.

This lubricating its pring n, the levers L L piston or valve J, c linderK, tube 9, oil-chamber H, and valves I I and their springs 43 i,substantially as and or the purpose herein shown and described.
